The bow is provided with a handle or grip 62, an arrow rest 12, a bow string 68. a bow string draw-bar 86, and a bow string draw-bar guide 14. The grip is located on the stock of the bow. The arrow rest and draw-bar guide are located on the side oi the bow at the upper end of the grip. The bow string draw-bar has a rearward portion 81 and a forward portion 88. The rearward portion of the draw-bar has a handle 9D and an arrow chuck 9|. The forward portion of the draw-bar is slidable backwardly in the draw-bar guide. Figure 1 shows the bow string stretched between the upper and lower ends of the bow, and the bow string has a knot B9 for properly locating the arrow chuck on the bow string with respect to the arrow rest. An arrow 52 is shown reposed on the arrow rest and the nook-end of the arrow is chucked in the arrow chuck with the bow string.

Shown in more detail in Figures 8, 9, l0 and l1, the side of the bow the upper end of the grip is beveled at S2 to afford clearance for the arrow and a seat for'the arrow rest block l2. The broad side of the bevel nearly parallels an arrow nocked on the bow string and placed against the broad side of the bevel as shown in Figure ll wherein broken lines indicate an arrow shaft necked on the bow string 58 which latter is positioned as when stretched between the ends of the how. The arrow rest block 'l2 is seated in the lower end or" the bevel and suitably fastened in place; a strong cement is usually employed as a fastener. A bolt hole 'i3 extends through the rear end portion of the arrow rest blc-ck and through the rear portion of the bow stock to receive the draw-bar guide clamp oolt 813. Referring also to Figures 12 to 17 inelusive, the right side wall Tl of the draw-bar guide 14 is clamped against the arrow rest block l2 with bolts 83 and 8f! and a clamp band 85, the bolt 84 having a ilat head countersunk in a depression 82 around the rear bolt hole in the wall 1T. Bolt S3 extends through aligned bolt holes 8! and 8l in the front end portions of the opposite side walls 'l5 and 'Il oi draw-bar guide and through the perforated front end portion of the clamp band 85. The draw-bar guide 14 is channel shape in cross section and has a draw-bar catch 85' which latter is located adiacent to the iront end .'9 and bottom 'I6 of the guide. The dra-webalcatch SG has the shape of a sleeve with square outside corners and serves also as a spacer sleeve on clamp bolt G3 and between the front end, portions of the opposite side walls l5 and l? of the guide. In Figure 15, broken lines 88 indicate the draw-bar reposed on the upper side of the catch 8S as when the draw-bar is positioned as shown in Figures l and 2. In. Figure 1G the front end 39 of the drawbar 86 is shown caught on the catch 8G as when the draw-bar is positioned as shown in Figures 3 and 4.

The arrow chuck 9i includes a plate portion 05 and a double bow string latch portion 92 Shown in more detail in Figures 29, 30, 31, 32, 36, 37, 38 and 39. The left edge portion 535 of the chuck plat-e is bolted onto the upper side of the draw-bar or may be otherwise securely attached to the draw-bar- The portion of the chuck plate proiecting over the right side of the draw-bar is slightly thicker than the nook-end of the arrow. The throat ll in the overprojecting portion of the chuck plate extends backwardly from the front edge of the plate between the rigid left chuck jaw 83 and the rigid right chuck jaw The throat l'l is slightly wider than the nook-end of the arrow is thick, and the throat receives the nook-end of the arrow and the bow string. The hole IH] in the rear edge portion of the chuck plate and located to the ieit of #the `longitudinal .center of thezthroat alifl., .receives Tthe ycross screw :a9 by awhich Llatter the string vlatch portion of sthe chuck is pivotally lmounted on the chuck. plate. The ystring latch portion of .the arrow .chuck 'induci'es the upper latch :jaw :$3 and .the lower` vlatch jaw ".95, ywhich vare :spaced vapart oy the Athroat $3.5. `The Alatch iaws 'are integral at the rear .98 whereltheitrigger limi is :attach-eti. The -throat :9.5 .is slightly'w'ider directly .between the .latch jaws than the chuck :plate .is thick. AThe latch jaws iare pivotally mounted `on v.opposite .sides of the chuck l.plate above 'and below the plate throat t0?! :with the cross screw .39 `.which ,latter extends through aligned holes in fthe latch 'jaws ano. hole ,I ,1B .in L

Vlnplacing the draw- 'cn 'the 'strung'bow as yshown in Figures rl i2, the how .may "be held in the vertical position with the lefthand .placed :around-the grip-so that the hase "knuckle of the iorenger will he under the 'front `end of ythe draw-*har guide, and the Adraw-bar may :he :held inthe horizontal position v'with the 'right hand placed around the'handle :so :that the-middle knuclzieiof the 'forefinger will be yunderthe rear end ofi the yarrow chuck, rand then lloyiplacingth'eidraW-har at about itsmidway porn tion in the draw-bar guide, the draw-bar may be pushed forward in the guide to enter the taut bow string into the chuck plate throat and the string latch grooves immediately above the knot 69. The bow string and knot will support the arrow chuck and rear end portion of the drawoar while the arrow is being chucked with the right hand. In chucking the arrow, the arrow may be gripped between the thumb and first two fingers of the right hand placed about six inches forward of the feathers, and by reaching the arrow around the right side of the bow to the front of the bow, the nook-end of the arrow may be turned cackwardly on the left side of the bow immediately above the arrow rest and the nock pushed into the throat of the arrow chuck to seat the nock on the latched bow string and with the odd colored feather positioned at nearly right angles with the bow string and nearly parallel with the upper side of the draw-bar. Some lateral pressure on the bow string by the hinged spring pressed latch jaws and soin@ additional pressure by the bow string against the left side of the nock groove when making the draw, holds the neck seated on the bow string during the draw. In making the draw to the shooting position shown in Figures 3 and 4, the bow may be held with the left hand as indicated above, but with the left arm extended outwardly, and with the lingers of the right hand curved around the i draw-bar handle, the draw-bar mair be drawn back until the front end thereof falls down behind the draw-bar catch, whereupon the draw may be discontinued to abut the front end of the draw-bar against the rear side of the catch as shown in Figure 16, which will hold the draw-bar in the shooting position for tazing aim. In ta"ing aim, the left hand remains on the grip of the bow and the left arm extended outwardly, but all of the left arm should be positioned clear of the shooting stroke of the bow string. rEhe fingers of the right hand may remain curved around the draw-bar handle, but the thumb is placed on the rear side of the end of the trigger extending downwardly on the left side of the draw-bar. Aim may be talrcn bv sighting down the draw-bar at the target, and the bow string may be loosed to shoot the arrow by pressing the trigger forward with the thumb of the right hand. Pressing the left end of the trigger forward moves the front ends of the hinged bow string latch jaws to the right which strips the bow string out of the latch grooves.

Referring to Figures 18 to 28v inclusive, the draw-bar ,ide i3 is channel shape in cross section and has the left side wall H4. the bottom 5, the right side wall portion |55, the draw-bar catch H9. the lug |28, and the rear section |2| of the band clamp, formed integral from a sheet metal blank such as blank H2 shown in Figure 27. The blank mav be cut from suitable sheet metal having the uniform thic"ness and strength desired. A. blank cut from tough sheet brass stock having a uniform thickness of about onesiXteenth of an inch may be used in making a guide for a draw-bar about ve one-eighths of an inch souare in cross section, for use on a bow having a draw weight in the neighborhood of forty-five to fty pounds. The lug and the rear section of the band clamp are integral with opposite ends of the side wall portion IS. The front section |22 of the band clamp has one end attached with a screw to the lug |20. The sections of the band clamp are connected with a bolt |23. The arrow rest block and the side wall portion ||B form the right side wall of the draw-bar guide. The arrow rest block is attached to the side wall portion ||6 and bottom H5 with flat head screws ||8, ||8 and ||8. The arrow rest block ||1 may be made of hard fiber, hard felt, hard rubber, plastic, or light metal. If preferred, a metal arrow rest block may be made with the lower portion extended the full length of the side wall portion i6, and the wall portion 6 may be formed without the lug |20, and the front section |22 of the band clamp may be attached with the screw to the front end of the metal arrow rest block. The draw-bar catch ||9 is located adjacent to the front end and bottom of the drawbar guide. The draw-bar retainer |24 is hinged at |25 to the bottom of the draw-bar guide, and the retainer may be pulled open as shown in Figure 1S for placing the draw-bar in the guide. The drawbar retainer may be moved to the closed position as shown in Figures 19, 20, 21 and 22, to retain the draw-bar in the guide. The draw-bar guide ||3 may be clamped on the bow in the place of the arrow rest block 12 and the draw-bar guide 14. The draw-bar guide |3 may be employed in providing an archers bow with a draw-bar such as draw-bar 88, or draw-bar |25.

The draw-bar guide 14, or guide 3, may be adapted for use on an archers bow made of metal, or an archers bow having a stock portion which is round or about round in cross section. The draw-bar guide can be adapted for mounting on a bow not having a bevel seat such as 6?, if a bevel is not desired.

The bow string draw-bar |25 has a rearward portion |21, an extended rear end portion |28, and a forward portion |29. The rearward portion of the draw-bar has a handle 80, an arrow chuck 5|, and is provided with a rear sight column |36. The handle and the arrow chuck are located on the draw-bar adjacent to the extended rear end portion |28. 'The rear sight column is located on the draw-bar a short distance forward of the arrow chuck. IThe forward portion of the drawbar is adapted to slide backwardly in a draw-bar guide having a draw-bar catch adjacent to its front end and bottom. rThe forward portion of the draw-bar has an under side which may be provided with a notch |3| as shown in Figure 26, or provided with two notches |3| and |33 as shown in Figure 43. The notches have shoulders |32 and |34 adapted to drop down behind the draw-bar catch in a draw-bar guide on the bow to hold the draw-bar in the drawn back position with the bow string latched in the arrow chuck. Bro`en lines 52 indicate a chucked arrow having a head 53. The forward portion of the draw-bar extends a short distance beyond the head of the chucked arrow, and the front catch notch |3| is located in the under side of the draw-bar a short distance back` of the arrow head 53. The catch notch |33 may be located for shooting a shorter arrow, or located for step-drawing the bow string of a heavy bow. A front sight |35 is mounted on the front end |38 of the draw-bar, and the sight is adjustable to the left or to the right of center a short distance. The rear sight column, shown in more detail in Figures 42, and 44 to 47 inclusive. has its lower end portion rigid with the downturned portion of the angular spring bracket support |31 which latter has an angled portion bolted onto the upper side of the draw-bar with an oppositely disposed angular anchor bracket 38.

In taking. aim with the rear sight positioned at about thev middle of the sight column,V the side. of the extended rear end portion of the draw-bar `may be rested against the neck or rested on the right shoulder. In taking aiml with the rear sight positioned along the upper portion of theA sight.; column, the side of the extended. rear end portion of the draw-bar may be rested against the point of the right shoulder or rested against the upper end of the right arin held close to the body, or rested lower down on the arm when the rear sight is positioned at the top end of the sight column.

The chuck plate Idd shown in Figure 34 is similar to chuck plate It except that the left chuck jaw is provided with a blade-like nock clamp spring MS attached with screw |52, which latter is threaded into the front end of the chuck jaw. The spring |158, shown in more detail in Figure 35, has an angled front end portion |49 and an angled rear end portion |513. The angled front end portion of the nock clamp spring has a perforation ii to receive the screw |52. The angled rear end portion of the nook clamp spring projects into a notch lill in the left chuck jaw to prevent the bow string from catching under the spring. rl'he nock clamp spring |48 affords a better grip on the arrow nook inserted in the throat of the chuck plate. An arrow chuck including chuck plate |46 may be employed on a draw-bar adapted i'or use on a hunting bow or adapted for use on a smaller bow.

A long heavy bow rather too strong to be drawn between the hands to the full shooting position for a twenty-eight inch long arrow, may be provided with a draw-bar guide 14, or guide H3, and a draw-bar |26 having an arrow chuck including chuck plate |46, and having the rear catch notch |33 located about six inches back from the front catch notch |3| for stepof Strong tie string having ay diameter about I0 ing.' the arrow: In stepedrawingf the; bowstring. the chuckedi arrowy andA latchedi bow string. may be.E drawn back. with they two hands on4 the. bow grip andi draw-bari handle. to. catch: the shoulder' lll" of the rear. catch4 notch4 on the draw-barV catch in` the draw-bar guide, and then by turnf ing the bow' down so that the front side ofthe bowy will be: toward'` the.l ground and placing thcright footv on. the rear side' or: the bowv grip;r`
